Nuclear magnetic resonance

Although, MRIs are known for being safer than procedures like CT scans and X-Rays there are some problems with using magnetic forces rather than radiation. Metal objects are very sensitive to the magnetic field that the machine produces, so any metal inside the room can be very dangerous. Patients who have pacemakers, or artificial body parts cannot partake in MRIs because they are too dangerous as the magnets…

Mammograms, ultrasounds, x-rays, and MRIs have helped women with breast cancer since 1895 (x-ray) 1956 (ultrasound) 1977 (MRI), and 1992 (mammogram). They have all been very beneficial to women. Breast cancer is the most common type of cancer in women. About one of three cancers are diagnosed. Cancer is a group of diseases that cause cells in the body to change and grow out of control. Most cancers will form a lump or mass in the breast, which is called a tumor. It is named after a part of the…

Our generation is faced with many growing global issues. Many of which have to do with solving medical and healthcare matters. As population increases, as does the risk of an increase in the spread of disease or epidemic growth. This calls for a growing need in biomedical engineering to develop the ideas to save humanity in the future. Biomedical Engineering is a complex process of solving, and then designing ways to solve problems in the human body using medicines or technology to improve…

Advantages of Endoscopic Septoplasty Endoscopic Septoplasty is associated with several advantages over the traditional one. It has many benefits such as magnification, suboptimal view of middle turbinate, better illumination and visualization. Separation of collagenous fibers connecting the perichondrium and periostium to underlying bone and cartilage is made visible with endoscope during surgical dissection. Mucosal disruptions are recognized immediately, and their size may be controlled using…

“He stopped breathing and turned blue!” exclaimed a young mother to the 911 operator. It was a cold winter night. As a mother went to check on her toddler son sleeping in his crib, she made a shocking discovery. The toddler had stopped breathing, his body was stiff as a stick, his eyes had popped wide open, and his skin had turned blue! The terrified mother immediately reached for the phone and dialed 911 for help. As she waited for the ambulance to arrive, the distraught mother performed CPR…

Purpose: The purpose of this memorandum is to present an analysis of the person(s) who would read this report. This report was created as one of the projects for a Writing for Technical Professional class. The goal of this project was to analyze the success of a medical innovation. My chosen topic was Focused Ultra Sound that enhance the drug delivery for treatment of CNS diseases. Audience Description: While writing this technical report, I imagined 2 types of people who would read it. The…

biomechanical signals. 5. Biomagnetic Signals:- MMG (Mechanomyogram) or MEG (Magneto-encephalogram) are the examples of biomechanical signals which are observed from the surface of muscles when it is contracted. Biomagnetic signals are obtained from the magnetic field produced by electrical currents occurred naturally in the brain of the living things. 6. Bio-optical Signals:- Bio optical signals can observe either naturally or the signals may be introduced to measure a biological…

Advantages of MRI: By choosing the appropriate pulse sequence and pulse sequence parameters, MRI has the ability of producing images by different contrast mechanisms giving it tremendous flexibility. Disadvantages of MRI: INFLAMMATORY PROCESS OF THE LUMBAR SPINE Spondylodiscitis: Introduction: Spondylodiscitis is a rare primary infection of the intervertebral disc with secondary infections of the vertebrae. It can lead to osteomyelitis of the spinal column. Predisposing factors include age,…

Contrast materials, otherwise known as contrast agents or contrast media, are used to get better pictures of the internal part of the body produced by x-rays, CT, MRI, and ultrasound. Frequently, contrast materials permit the radiologist to differentiate normal from abnormal disorders/illnesses. Contrast agents are not tints that forever discolor internal organs. They are substances that for a short period of time change the way x-rays or other imaging devices act together with the body. When…

Many people may think that MRI’s and CT’s are similar because they both provide images on the inside of the human body. These two machines work differently and are used differently. MRI scans are used in hospitals all around the world. Strong magnetic fields and radio waves are used to create images of organs and tissues in the human body. The MRI scan helps the doctor see if there are any unhealthy organs or tissues in the body. MRI scans are used for injuries of the back or any other joint…
